function z = isocomplex(q, a)
% ISOCOMPLEX    Construct a complex number from a quaternion, with the same
%               modulus and argument as those of the quaternion. The result
%               will be in the upper half of the complex plane unless the
%               second (optional) parameter is supplied - in this case, the
%               optional parameter is a reference unit quaternion defining
%               the direction of the positive imaginary axis of q.
%               The optional argument must be either the same size as q or
%               be a scalar (in which case the same value is used for all
%               elements of q).
